Storage device authentication

ABSTRACT

Systems and methods authenticate storage devices. In one implementation, a computer-implemented method is provided for authenticating a storage device. According to the method, a manifest that identifies a destination is receive. A transfer station reads a digital signature from the storage device. The digital signature is validated and, based on the validation of the digital signature, a transfer of one or more files from the storage device via the transfer station is authorized to the destination identified in the manifest.

BACKGROUND

This application is a continuation of U.S. Pat. Application Serial No.16/931,686, filed Jul. 17, 2020, which is a continuation of U.S. Pat.Application Serial No. 16/112,487, filed Aug. 24, 2018, now U.S. Pat.No. 10,719,455, which is a continuation of U.S. Pat. Application SerialNo. 15/050,082, filed Feb. 22, 2016, now U.S. Pat. No. 10,061,716, whichis a continuation of U.S. Pat. Application Serial No. 12/453,614, filedMay 15, 2009, now U.S. Pat. No. 9,270,683, which are hereby incorporatedby reference herein in their entirety.

Anyone who wishes to transfer data over a network to a storage locationis faced with the question of how to securely transfer the data in atimely manner. In cloud computing, for example, developers and otherusers access a service that provides dynamic and resizable computecapacity without requiring the developers to have knowledge of, orcontrol over, the technological infrastructure that provides theservice. Developers, for example, that use cloud computing sometimeshave a need to upload substantial amounts of data to a network storagelocation.

To access a network, for example, a developer may use a fiber opticline, such as a T1 line. A T1 line can carry data at a rate ofapproximately 1.544 megabits per second. Using a single T1 line tocontinuously transfer data, it would take approximately an entire monthto transfer 400 gigabytes of data. If a developer wishes to transferdata at a faster rate or does not wish to burden a T1 line with a largedata transfer, the developer is faced with the question of whether toacquire additional T1 lines. Acquiring additional T1 lines comes atadditional expense. Furthermore, the developer may not have a need forthe increased data capacity for day-to-day operations, making acquiringadditional T1 lines cost inefficient.

Similar to developers, others may also want to transfer data to anetwork storage location. For example, others may wish to simply backuptheir data with a copy that resides at another location. These users mayalso transfer large amounts of data over a network, which can take asubstantial amount of time to transfer. Consequently, any entity thatwishes to transfer a large amount of data is faced with the question ofhow to securely transfer the data in a reasonable amount of time withoutunduly burdening its own network resources or without incurring anadditional expense to obtain a greater data transfer rate capacity.

To avoid data transfer delays and capacity limitations, individuals whowish to transfer large amounts of data to network storage devices cansimply avoid transferring their data over a network altogether. Instead,these individuals can store their data on portable media and send themedia by courier to a location where the data is transferred from themedia. Since the data is transferred directly from the media, transferrates to a network storage device are dramatically faster. However, whensending data in this manner, the recipient of the media (e.g., theservice provider) who loads the data to a customer’s account may want toconfirm that the media was sent pursuant to the customer’sauthorization. Without proper safeguards, an imposter could send mediathat includes malicious code or code that is designed to stealinformation, which could then be unsuspectingly transferred to a networkstorage device.

In view of the foregoing, there are data transfer rate and capacitylimitations that limit the amount of data that can be transferred over anetwork during a given time period. As an alternative to transferringdata over a network, one may send data on physical media for directtransfer, but safeguards are needed to ensure that, for example, onlydata that is actually authorized is transferred. Therefore, there is aneed for improved systems and methods that overcome the above problems.

DETAILED DESCRIPTION

The following detailed description refers to the accompanying drawings.Wherever possible, the same reference numbers are used in the drawingsand the following description to refer to the same or similar parts.While several exemplary embodiments are described herein, modifications,adaptations and other implementations are possible. For example,substitutions, additions or modifications may be made to the componentsillustrated in the drawings, and the exemplary methods described hereinmay be modified by substituting, reordering, or adding blocks to thedisclosed methods. Accordingly, the following detailed description isnot limiting of the disclosed embodiments. Instead, the proper scope isdefined by the appended claims.

Disclosed embodiments provide computer-implemented systems and methodsfor identifying and authenticating storage devices. Storage devices mayinclude any media, such as universal serial bus (USB) drives, CD-ROMs,DVD-ROMs, other optical discs, etc., that can store data. Disclosedembodiments may make use of one or more storage devices to transmit, forexample, hundreds of gigabytes or terabytes of data via physical media.Furthermore, disclosed embodiments provide systems and methods whereby arecipient of a storage device can identify and authenticate the sender.

In one embodiment, a sender who wants to have his or her data uploadedto a remotely accessible storage device, such as a network storagedevice may store the data on a portable storage device, such as aninternal hard drive, external USB hard drive, flash memory device, orcompact disc, among other possibilities. The sender may create amanifest that includes an identifier of a destination or storagelocation, such as an account, a unique identifier of the sender, and areturn shipping address. Next, the sender may electronically transmitthe manifest to a provider of the network storage device. The providerof the network storage device may return a unique device identifier,such as a device or job identifier. The sender may sign, for example,the manifest, the device or job identifier, and/or the sender identifierwith a secret key to create a digital signature. Creation of the digitalsignature may be according to any number of cryptographic techniques(e.g., Public Key Infrastructure (PKI), etc.). The resulting digitalsignature may be copied to a location on the portable storage device,such as the root directory. The sender may then pack and ship thestorage device to the provider.

Once at a data center of the provider, the provider may mount thestorage device to a port of a transfer station or load the storagedevice via a drive of the transfer station. The provider may thenidentify and authenticate the storage device using the digital signaturethat was previously saved to the storage device. For example, theprovider may send the digital signature to an external service tovalidate the signature and confirm that the sender was in possession ofthe secret key. As part of the validation, the external service maycheck the digital signature with the secret key, which may be in theexternal service’s possession. The external service may retrieve thecorrect secret key by using, for example, a public key identifier, whichmay be stored on the storage device. Once verified, the provider maythen transfer the data from the storage device to the network storagedevice via the transfer station. Accordingly, disclosed embodimentsallow the provider to authenticate that the storage device came fromsomeone in control of the sender’s secret key.

Consistent with a disclosed embodiment, a method is provided forauthenticating a storage device. The method may include receiving, froma sender, a manifest. The manifest may identify a destination. Themethod may further include validating a format of the manifest andtransmitting, to the sender, a device identifier. The method may furtherinclude receiving the storage device from the sender. The storage devicemay have a digital signature stored thereon. A transfer station may readthe digital signature from the storage device. The method may furtherinclude validating the digital signature, retrieving the manifest basedon the device identifier, and authorizing, based on the validation ofthe digital signature, a transfer of one or more files from the storagedevice via the transfer station to the destination identified in themanifest.

Consistent with another disclosed embodiment, a computer-implementedmethod is provided for authenticating a storage device. The method mayinclude receiving a manifest. The manifest may identify a destination.The method may further include reading, by a transfer station, a digitalsignature from the storage device, validating the digital signature, andauthorizing, based on the validation of the digital signature, atransfer of one or more files from the storage device via the transferstation to the destination identified in the manifest.

Consistent with yet another disclosed embodiment, a system is providedfor authenticating a storage device. The system may include a serverthat is in communication with a network. The server may include aprocessor and a data store. The system may further include a transferstation in communication with the network. The transfer station may beoperable to receive a manifest that identifies a destination, read adigital signature from the storage device, validate the digitalsignature, and authorize, based on the validation of the digitalsignature, a transfer of one or more files from the storage device tothe destination identified in the manifest.

Consistent with other disclosed embodiments, a computer-readable storagemedium may store program instructions, which when executed by aprocessor, perform any of the above-described methods.

It is to be understood that both the foregoing general description andthe following detailed description are exemplary and explanatory onlyand are not restrictive of disclosed embodiments, as claimed.

FIG. 1 is an example of a system 100 for authenticating a storagedevice, consistent with a disclosed embodiment. System 100 may providefunctionality for a network storage provider to authenticate a storagedevice. As shown in system 100, terminals 102-106, storage server 110,service server 118, and transfer stations 120-124 are connected to anetwork 108. One of skill in the art will appreciate that although threeterminals, one storage server, one service server, and three transferstations are depicted in FIG. 1 , any number of these components may beprovided. Furthermore, one of ordinary skill in the art will recognizethat one or more components of system 100 may be combined and/or dividedinto subcomponents. For example, functionality provided by the transferstations and the storage server may be combined and/or functionalityprovided by the service server and storage server may be combined.

Network 108 provides communications between the various components insystem 100, such as terminals 102-106, storage server 110, serviceserver 118, and transfer stations 120-124. In addition, terminals102-106, storage server 110, service server 118, and/or transferstations 120-124 may access legacy systems (not shown) via network 108,or may directly access legacy systems, data stores, or other networkapplications. Network 108 may be a shared, public, or private network,may encompass a wide area or local area, and may be implemented throughany suitable combination of wired and/or wireless communicationnetworks. Network 108 may further comprise an intranet or the Internet.

Terminals 102-106 may be any type device for communicating with storageserver 110 and/or service server 118 over network 108. For example,users of terminals 102-106 may access and/or receive data from storageserver 110 and/or service server 118. Terminals 102-106 may be personalcomputers, handheld devices (e.g., PDAs, cellular phones, etc.), or anyother appropriate computing platform or device capable of exchangingdata with network 108. Terminals 102-106 may each include a processor(not shown), a memory (not shown), and one or more ports (not shown) formounting storage devices (e.g., USB drives) and/or one or more drivesfor loading media (e.g., optical discs). Furthermore, terminals 102-106may execute program modules that provide one or more graphical userinterfaces (GUIs) for interacting with network resources, such asstorage server 110 and/or service server 118.

Storage server 110 may comprise a general purpose computer (e.g., apersonal computer, network computer, server, or mainframe computer)having one or more processors that may be selectively activated orreconfigured by a computer program. Storage server 110 may beimplemented in a distributed network. For example, storage server 110may communicate via network 108 with additional storage servers (notshown), which may enable storage server 110 to distribute processes forparallel execution by a plurality of storage servers. Collectively,storage server 110 and these additional storage servers may comprise astorage area network (SAN). Alternatively, storage server 110 may bespecially constructed for carrying-out methods consistent with disclosedembodiments.

Storage server 110 may include a processor 112, a memory 114, and a datastore 116. Memory 114 may comprise one or more memory or storage devicesthat store data as well as software. Memory 114 may also comprise, forexample, one or more of RAM, ROM, magnetic storage, or optical storage.Memory 114 may store program modules that, when executed by processor112, perform one or more processes for enabling access to data residingon data store 116.

Data store 116 may comprise a plurality of storage devices, such as diskstorage devices, optical storage devices, etc. For example, data store116 may comprise multiple disk drives that combine to form a disk array.The disk array may include, for example, a disk array controller, acache, disk enclosures, and a power supply. The disk array controllermay connect to network 108 via a port (not shown), which may serve as aninterface between the disk array controller and network 108.

Storage server 110 may host various data, including data providingInternet sites, as well as provide functionality for authenticatingusers and providing access to the data. For example, data store 116 maystore pages that are displayable by a computer executing software, suchas an Internet browser. Storage server 110 may allow users at, forexample, terminals 102-106 to access Internet sites being hosted bystorage server 110. Furthermore, storage server 110 may allow providersof Internet sites (e.g., developers, site administrators, etc.) beinghosted by storage server 110 to access, modify, and load data ontostorage server 110. These users may access storage server 110 overnetwork 108 through an Internet browser or software application runningon any one of terminals 102-106. In some embodiments, the data may beaccessible through other network mechanism, such as through anapplication program interface (API) of a Web Service.

Storage server 110 may transmit a document (e.g., a JavaScript ObjectNotation (JSON) document, an Extensible Markup Language (XML) document,or a web page) that is accessible by an Internet browser executing onone of terminals 102-106. The document may include options for a user tolog onto a secure site provided by storage server 110. For example,users may log onto a secure site provided by storage server 110 bysupplying credentials, such as a username and a password. Because theInternet site may use a secure communication environment, such as anHTTPS (hypertext transfer protocol secure) environment to transfer dataover network 108, data transfer is assumed to be secure.

Service server 118 may comprise a general purpose computer (e.g., apersonal computer, network computer, server, or mainframe computer)having one or more processors (not shown) that may be selectivelyactivated or reconfigured by a computer program stored in memory (notshown). Service server 118 may be implemented in a distributed network,such that service server 118 may communicate via network 108 withadditional service servers (not shown). Alternatively, service server118 may be specially constructed for carrying-out methods consistentwith disclosed embodiments.

In operation, service server 118 may coordinate operations of a servicefor authenticating storage devices. For example, service server 118 mayallow users at terminals 102-106 to access the service to submit and/ormonitor requests to ship physical media to a provider that will uploaddata from the physical media to storage server 110. For example, a userwho wants to have his or her data uploaded to storage server 110 maysubmit a request from one of terminals 102-106. The request may includea manifest pertaining to the request, which may be in the form of amanifest file that identifies the user and specifies a storage locationfor the data. Manifest files are discussed below in further detail.Service server 118 may further store the manifest and return data and/orinstructions to the user at one of terminals 102-106. For example, theinstructions may indicate an address to which the user should ship astorage device, such as an external USB hard drive. Service server 118may further provide status information to users at terminals 102-106, asdiscussed below in further detail.

Transfer stations 120-124 may comprise general purpose computers (e.g.,personal computers, network computers, servers, or mainframe computers)having one or more processors (not shown) that may be selectivelyactivated or reconfigured by a computer program. Transfer stations120-124 may communicate via network 108 with storage server 110.Furthermore, in some embodiments, transfer stations 120-124 mayimplement restrictive safeguards such that data may only be loaded fromtransfer stations 120-124 to storage server 110. Transfer stations120-124 may include one or more access ports (not shown) and/or drives(not shown) for mounting or loading storage devices, such as USB drives,CD-ROMs, DVD-ROMs, other optical discs, etc. For example, transfertechnicians may mount or load storage devices to the access ports and/ordrives of transfer stations 120-124. Once a storage device is attachedor loaded to one of transfer stations 120-124, the storage device may beauthenticated by reading a signature file saved to the storage device.Further details concerning the authentication of storage devices arediscussed below.

FIG. 2 is a flow diagram of an example of a routine 200 for preparingand authenticating a storage device, consistent with a disclosedembodiment. Routine 200 provides an overview of a process in which datafiles are stored on a storage device, which is then transported,authenticated, and uploaded to a network storage location (e.g., storageserver 110). Further details regarding the process are discussed inconnection with FIGS. 3 and 4 .

In block 202, a user at one of terminals 102-106 may store data on astorage device. The data may include, for example, data files intendedfor upload to a network storage device, such as storage server 110. Theuser may transfer the data from terminal 102 to a portable storagedevice, such as a USB drive, CD-ROM, DVD-ROM, other optical disc, etc.,which may be mounted or inserted into a port or drive that is incommunication with terminal 102.

In block 204, the user may store a digital signature on the storagedevice. The user may transfer the digital signature to the storagedevice via terminal 102. For example, the user may store the digitalsignature on the root directory of the storage device or in a particularfolder.

In block 206, the user may ship the storage device to a provider thatwill host the data on a network storage device, such as storage server110. As part of the process, the user may pack the storage device, printa shipping label, and transfer the package to a shipping service. Theshipping service may then physically transport the package to theprovider using one or more modes of transportation (vehicles, airplanes,trains, ships, etc.).

In block 208, the provider may receive the storage device from theshipping service. Next, in decision block 210, the provider maydetermine whether the storage device includes a valid digital signature.To determine whether the storage device includes a valid signature, theprovider may mount or load the storage device to one of transferstations 120-124. Once mounted or loaded, one of transfer stations120-124 may read the digital signature and determine whether the digitalsignature is valid. As part of the validation process, transfer stations120-124 may access data residing on, for example, service server 118. Ifthe digital signature is valid, then the process proceeds to block 208.If the digital signature is not valid, then the process ends. Furtherdetails regarding authenticating digital signatures are discussed below.

In block 212, the provider may upload the data files to a destination,such as an account associated with the user. For example, the providermay use one of transfer stations 120-124 to transfer the data files overnetwork 108 to storage server 110.

Although the above discussion and the following discussion refers to theprovider of storage server 110 as being the party that operates transferstations 120-124, one of ordinary skill in the art will recognize that athird party could perform similar functions as the provider or on theprovider’s behalf.

FIG. 3 is a flow diagram of an example of a routine 300 for preparing astorage device, consistent with a disclosed embodiment. Routine 300provides further details regarding a process in which a user prepares astorage device for shipment.

Prior to the start of routine 300, a user may be authenticated by, forexample, service server 118. For example, prior to the start of routine300, service server 118 may transmit a document (e.g., a web page) thatis accessible by an Internet browser executing on one of terminals102-106. The document may include options for a user to log onto asecure site provided by service server 118. The user may log onto thesecure site by supplying credentials, such as a username and a password.Once authenticated, routine 300 may begin.

In block 302, the user may copy data to a portable storage device. Asdiscussed above, a user at one of terminals 102-106 may store data thatmay include, for example, data files intended for upload to a networkstorage device, such as storage server 110. The user may transfer thedata from, for example, terminal 102 to a portable storage device, suchas an internal hard drive, an external USB hard drive, flash memorydevice, CD-ROM, DVD-ROM, other optical disc, etc., which may be mountedto a port or loaded into a drive that is in communication with terminal102. In some implementations, the storage device may need to support aparticular file system format (e.g., FAT32, ext3, NTFS, HFS) and eachfile that is stored on the storage device may need to be less than orequal to a particular file size (e.g., five gigabytes). In still otherimplementations, the user may encrypt the data that is stored on thestorage device.

In block 304, the user may create a manifest, which may identify thecontents of the storage device. The user may create the manifest at, forexample, terminal 102, using a text editor. In one implementation, themanifest may comprise a text file. In other implementations, the usermay use a web user interface (UI) to create the manifest.

The manifest may be of a particular file format (e.g., YAML, XML, JSON,etc.) and may include several pieces of information. For example, themanifest may include an identifier of a destination or storage location,such as an account. The manifest may further include a public keyidentifier (ID) of the user or a recipient of the storage device. Thepublic key ID may constitute a string that uniquely identifies the useror recipient. In some implementations, any unique identifier of theuser, sender, recipient, or the storage device may be used. Furthermore,the public key ID may have a corresponding secret key ID. The secret keymay be used to generate a digital signature, which is discussed below infurther detail, to authenticate the storage device.

The following is an example of a manifest (e.g., a manifest file named“manifest123.txt”):

       destination: my-account        accessKeyId: 0FF36Q3V0WFFSRW0EXG2       manifestVersion: 1.0        returnAddress:              name: Mr. Smith               street1: 123 Main Street              city: Seattle               stateOrProvince: WA              postalCode: 98104               phoneNumber: 206-555-1000              country: USA

In the above example, the manifest file specifies an identifier of adestination, e.g., a single storage location for uploading files (e.g.,“my-account”). The manifest further includes an access key ID (e.g.,“0FF36Q3V0WFFSRW0EXG2”), a manifest version (e.g., “1.0”), and a returnaddress. The provider may use the return address so that, once thestorage device has been processed, it may be returned to the user.

The above is merely illustrative and manifests may include additionalinformation or less information than shown above. For example, themanifest may include additional information, such as one or more contenttypes for files, metadata, instructions to ignore certain files (e.g.,ignore files with a particular extension), and may specify storagelocations for certain files (e.g., all files of type “.jpg” should beuploaded to a folder named “/images/”). For additional security, themanifest include a disk inventory (e.g., a list of files and checksums).In some embodiments, a manifest may not necessarily include all of theinformation shown in the exemplary manifest file. For example, in someimplementations, after processing, the storage device may not beenreturned and may instead be destroyed. In such an implementation, thereturn address may be omitted from the manifest.

In block 306, the provider of a data hosting service (e.g., a providerof storage server 110) may receive the manifest from the user via asecure channel. For example, the user may send the manifest over network108 from terminal 102 to service server 118. In one implementation, themanifest may be submitted via email as an attachment. In otherimplementations, the manifest may be submitted via a web UI or a web API(e.g., implemented through a protocol such as SOAP).

In some implementations, in block 306, the provider may further receivean encryption key from the user via the secure channel. For example, inblock 302, the user may have encrypted the contents of the storagedevice. Accordingly, the provider (e.g., a provider of storage server110) may later use the encryption key to decrypt the contents of thestorage device.

In block 308, service server 118 may validate the format of the manifestand/or content of the manifest. For example, service server 118 mayinvoke a service to determine whether the manifest includes a minimumamount of required information and whether the manifest is properlyformatted. Furthermore, as part of the validation process, serviceserver 118 may confirm that the user has identifier a valid storagelocation or locations (e.g., an account) in the manifest.

In block 310, service server 118 may create a device or job ID. Forexample, one of transfer stations 120-124 may use the job ID to retrievethe manifest and/or to identify the transfer job at a later time. Inother implementations, service server 118 may not need to assign a jobID, because the user may have provided the job ID in block 306. Forexample, service server 118 may have previously assigned the user aglobally unique identifier (GUID), which service server 118 maysubsequently use to retrieve the manifest and the job ID.

In block 312, service server 118 may store the manifest. Service server118 may optionally store the encryption key as part of this block.Optionally, service server 118 may transmit the job ID to storage server110.

In block 314, service server 118 may transmit the job ID to the user atterminal 102 via network 108. For example, service server 118 may send asuccess message (e.g., an e-mail message) to the user with the job ID.

In block 316, the user may create a digital signature. The digitalsignature may uniquely identify the transfer job and be used toauthenticate the request at a later time. To create the digitalsignature, the user may need a job ID, the manifest, a public key ID,and a secret key ID.

In one implementation, as part of the process of creating the digitalsignature, an encryption service being executed at terminal 102 or beingprovided over network 108 via, for example, service server 118, may bepassed parameters, such as the manifest (e.g., “manifest123.txt”), thejob ID (e.g., 3343), and the user’s public key ID (e.g.,0FF36Q3V0WFFSRW0EXG2) or the recipient’s public key ID. The service mayprompt the user for the user’s secret key ID. In other embodiments, theservice may prompt the user for a secret key ID of a recipient of thestorage device, such as a provider of a network storage device.

After entering the secret key ID, the service may create a digitalsignature, using the secret key ID to sign the passed parameters (e.g.,the manifest, the job ID, and/or the public key ID). Accordingly, as thedigital signature is based on the manifest, the digital signature can belater used to validate that the manifest on the storage device is thesame as the manifest that was received by service server 118 in block306 (e.g., the digital signature can validate that the manifest at thetime of the signing and the one sent to the provider are byte-for-byteidentical).

In block 318, the user may copy the digital signature to the storagedevice. For example, the user may use terminal 102 to store the digitalsignature on the root directory of the storage device or in a particularfolder. In addition, as part of block 318, the user may store the job IDand/or the public key ID to the storage device, along with the digitalsignature.

In one implementation, the job ID, the public key, and the digitalsignature may be stored separately on the storage device. In anotherimplementation, the user may create a signature file that comprises thejob ID, the public key ID, and the digital signature. The name of thesignature file may have a required format (e.g., the signature file maybe required to be named “Signature”).

As part of block 318, the user may also copy the data files that theuser wishes to transfer from terminal 102 to the storage device. Copyingthe data files may occur before or after this step, as deemedappropriate by the user. As the storage device includes the job ID, theprovider may use the job ID to retrieve the manifest from service server118. In a preferred embodiment, the actual manifest is not stored on thestorage device.

In block 320, the user may pack the storage device and ship the storagedevice to the provider, which will host the data on network storage,such as storage server 110. For example, the user may pack the storagedevice, print a shipping label, and transfer the package to a shippingservice provider. The shipping service provider may then physicallytransport the package using one or more modes of transportation(vehicles, airplanes, trains, ships, etc.). In other implementations,service server 118 may convert the digital signature into a barcode suchthat a package or physical object itself could be authenticatedaccording to disclosed embodiments.

FIG. 4 is a flow diagram of an example of a routine 400 forauthenticating a storage device, consistent with a disclosed embodiment.Routine 400 provides further details regarding a process in which aprovider receives a storage device, authenticates the storage device,and transfers the data from the storage device. Accordingly, routine 400may occur after routine 300, for example.

In block 402, the provider may receive the storage device at a facility.For example, as part of the intake process of the storage device, theprovider may check the package (i.e., verify that the package is on anexpected package list), check where the package originated from, andperform a security check before forwarding the package to a data center,which may house transfer stations 120-124.

In block 404, the provider may create a ticket for the storage device(i.e., assign the package a tracking number). For example, receipt ofthe package may be input into a terminal (not shown) in communicationservice server 118. Accordingly, service server 118 may create a ticketnumber that is associated with the ticket and the package.

In block 406, the provider may mount the storage device to one oftransfer stations 120-124, such as transfer station 120. As discussedabove, transfer stations 120-124 may include one or more access ports(not shown) or drives for mounting or loading storage devices, such asinternal hard drives, USB drives, CD-ROMs, DVD-ROMs, other opticaldiscs, etc.

In decision block 408, transfer station 120 may read the signature filefrom the storage device. For example, the job ID and/or the public keyID may be stored together as part of a signature file. Alternatively, asdiscussed above, in other embodiments, transfer station 120 may read thejob ID, the public key ID, and/or the digital signature from the storagedevice, which may each be stored as separate files.

As part of block 408, transfer station 120 may send the digitalsignature (either separately or as part of a signature file) via network108 to an external service to validate the digital signature, which mayverify that the sender was in possession of the secret key. For example,the external service may be provided by, for example, service server118. As part of the validation, the external service may check thedigital signature with the secret key (e.g., the user’s secret key or asecret key of the recipient), which may be in the external service’spossession (e.g., stored by service server 118). The external servicemay retrieve the correct secret key by using, for example, the publickey ID, which transfer station 120 may pass to the external service.Accordingly, the external service may authenticate that the storagedevice came from someone in control of the user’s secret key ID.

If the digital signature is valid, the external service may transmit a“success” result to transfer station 120 and the process proceeds toblock 410. If the digital signature is not valid, then the process ends.

In block 410, storage server 110 may perform a process to authorize thetransfer of the files to the user’s account from transfer station 120.For example, the user’s account may only authorize the user to uploadfiles. However, since transfer station 120 is going to perform theupload, transfer station 120 may need authorization, because the user isnot in control transfer station 120. Accordingly, in block 410, asecurity token service may submit a request to, for example, storageserver 110 or another service, in order to allow transfer station 120 toupload data to the user’s account. In some implementations, block 410may be optional as such authorization may not be required and transferstation 120 may implicitly have authorization to upload data.

In block 412, transfer station 120 may transfer or upload the data filesto an account or storage location associated with the user. For example,the provider may use one of transfer stations 120-124 to transfer thedata files over network 108 to storage server 110. Optionally, as partof block 412, transfer station 120 may retrieve an encryption key sentby the user from service server 118 to decrypt the contents of thestorage device.

The transfer of the files may occur according to the manifest. Forexample, transfer station 120 may retrieve the manifest from serviceserver 118 according to the job ID. At a minimum, the manifest mayindicate a destination, such as a single storage location (e.g., adirectory of the user’s account) of storage server 110 where the filesshould be uploaded. The manifest may further include additional rules orparameters, which may designate, for example, certain storage locationsfor certain files (e.g., all image files are to be uploaded to anexisting directory named “/images/” on the user’s account).

In block 414, transfer station 120 may create one or more log files. Forexample, transfer station 120 may create an upload report, which may beuploaded to the user’s account on storage server 110. The upload reportmay include checksums and file stamps (e.g., date and time of upload).For example, the report may provide, on a line item basis, for everyfile, an upload time, name on disk, disk in storage server 110, achecksum, a status code, a number of bytes, etc.

Transfer station 120 may further create a history log file that may beretained by the provider for billing purposes. The provider may use thehistory log file to determine a monetary charge for uploading the data(e.g., a monetary charge per unit of uploaded data). Furthermore, theprovider may retain the history log for purposes of dispute resolution.Transfer station 120 may transmit the history log file to, for example,service server 118 for storage. Transfer station 120 may further createan error log file that may identify errors that occurred during theupload and/or a performance log file that reflects performance data(e.g., how long each file took to upload, how many retries, etc.) forefficiency monitoring purposes.

In block 416, transfer station 120 may transmit an update request toservice server 118 in order to update the ticket corresponding to thejob. For example, service server 118 may update the ticket to indicatethat the job has been successfully completed.

In block 418, service server 118 may send a notification to the userthat the process has been successfully completed. The notification maybe sent, for example, via an e-mail message to an e-mail addressassociated with the user. Furthermore, the notification may indicatethat the provider will ship the storage device (e.g., provide a trackingnumber for the return package) or may indicate that the job has beencompleted and the storage device will be destroyed.

During the above process, service server 118 may provide statusinformation to the user at terminal 102. Status information may indicatewhere a storage device is physically located or a status of a job (e.g.,mailroom, data room, job processed, in progress, complete, log access)or may provide information regarding errors during an upload process(e.g., certain files were corrupted, so the user can upload thosespecific files over network 108).
